SUPPOSlTORY-MACHINE.

SPECIFICATION forming part of Letters Patent No. 342,236, dated May 18,1886.

(No model.)

To aZZ whom it may concern.-

Be it known that I, FERDINAND G. UIILIoII, of the city of St. Louis, inthe State of Missouri, have invented a certain new and usefulImprovementin Apparatuses for Making Suppositories, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification, and inwhich-- Figure l is a side view of the cylinder and the dischargepiston.Fig. 2 is an axial section of the cylinder and the two pistons. V Fig. 3is a side view of the cylindrical body,which is out into lengths, asshown in Fig. 4, each of which is pointed by the instrument of which aperspective view is shown in Fig. 5, the operation being illustrated bythe sectional view shown in Fig. 6. Fig. 7 shows one of thesuppositories completed. Fig. 8 is a side View of a modification of theinstrument shown in Fig. 5, the same consisting of duplicate parts, asseen in Fig. 9, held together by a band or ring.

A is a cylinder, open at one end, and having at the other end a head, a,which is bored for the passage of the rod b of a piston, B. Thepiston-rod has a knob, b, by which it is held.

A is the flaring mouth of the cylinder A. This flaring mouth is notessential; but it is advantageous, as increasing the facility with whichthe matcrialis put into the cylinder.

0 is a removable piston, having a rod, 0, and a knob, o. The piston O isused for the compression of the material in the cylinder A.

\Vhen the material D is placed in the cylinder, it is in a softcondition, so that it is read ily compressed into a dense mass. Thetemperature is then reduced to give firmness or hardness to the mass.This may be done in any manncrfor instance, by the immersion of thecylinder in cold water. Then the stick or cylinder 1) is forced from thecylinder A by means of the piston B. The cylindrical mass 1) is then cutinto pieces, d, of proper length.

E is a metal thimble, having a recess, e, of the proper form to give therequired shape to the end of the suppository d, whatever the diameter ofthe piece (I may be. Thus the same thimble may be used for a number ofcylinders A of various sizes.

In the use of the thimble it is first heated, and then the end of thepiece d is inserted in the thimble and pressed down. turned within thethimble to assist the operation.

In the modification shown in Figs. 8 and 9 the thimblc is made in twoparts, E E, which are held together when in use by a ring or collar, F.(See Fig. 8.) In this case the recess e is cylindrical in its outer partand conical at the point. The two parts E may be taken apart to removethe suppository.

I claim as my invention- In a machine for making suppositories, thecombination, with the cylinder A and the re movable piston O forcompressing the material therein, of the ejector, consisting of thepiston B and the rod b, of the requisite length for expelling thematerial from the filling end of the cylinder, substantially as setforth.
